Cam Newton was all smiles on his first day on the job as an NFL quarterback.

Newton showed off his easy demeanor and passing arm as the first-pick of the NFL draft practiced for the first time as the Carolina Panthers hit the field Saturday at their training camp in Spartanburg, S.C. These photos from Associated Press photographer Chuck Burton tell the story of the former Auburn quarterback.

"Cam Newton had full-scale charm going today in interview," wrote Charlotte Observer columnist Scott Fowler after an early interview session, the day after Newton signed a four-year $22 million contract.

A tweet from the Carolina PR staff said this:

"First highlight play of first practice just happened, with Armanti Edwards making circus catch on a deep ball lofted skyward by Cam Newton."
